Answer:

Area of a regular pentagon = pa/2, where p = the perimeter and a = the apothem. If you don't know the perimeter, calculate it from the side length: p = 5s, where s is the side length.

The number of question on an exam varies with the number

alekssr [168]

Answer:

$t=5x$

Step-by-step explanation:

So the number of questions in an exam varies with the number of minutes to take the exam.

For each question there are 5 minutes allotted.

Lets say that there are 'x' number of questions in the exam and 't' is the total time taken to finish the exam, in minutes. So the time taken to complete the exam would be

$5 \times x=5x$

Therefore, the equation relating the time taken to complete the exam and the number of questions is given by:

$t=5x$

So there are two variables in the equation, 't', and 'x':

t - time taken to complete the exam

x - number of questions on the exam

Solve for all solutions of the equation. Show all work for full credit. X^3-8=0

Marianna [84]

Answer:

Step-by-step explanation:

Hello

We can notice that

$2^3=2\times 2\times 2=8$

so 2 is one solution, we can put (x-2) in factor

$x^3-8=(x-2)(x^2+2x+4)\\ \\ \Delta=2^2-4\times4=4-16=-12$

So there is no other real solution.

Thanks

Use slopes and y-intercepts to determine if the lines -5x – 4y = -3 and -5x – 5y = -3 are parallel

Bogdan [553]

Answer:

Not parallel.

Step-by-step explanation:

If the slopes are the same they are parallel.

So we convert each one to slope-intercept form:

-5x - 4y = -3

-4y = 5x - 3 Divide both sides by -4:

y = -5/4 x + 3/4.

Slope = -5/4.

-5x – 5y = -3

-5y = 5x - 3 Divide both sides by -5:

y = -1 x + 3/5.

Slope = -1.

The slope are different - so NOT parallel.
